SMOKING-PIPE.

Application filed December 31, 1915.

To all whom it may concern:

Be it known that 1, James A. IRVING, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Smoking-Pipes, of which the following is a speciiication.

Une of the greatest objections to the use of the ordinary pipe is the accumulation of the wet, soggy, objectionable heel at the bottom of the pipe bowl. The accumulation of this heel is extremely disagreeable to the ordinary pipe smoker. Another great obj ection to the ordinary pipe is the manner of charging it with tobacco. The unburned portion of the previous charge must first be removed, and the heel'cleaned out before a fresh charge of tobacco can be placed therein. This is not only a dirty job, but results in a great waste of tobacco. Another objection to this type of pipe is that the fire or lighted portion of the tobacco is likely to be accidentally detached from the body of the charge and discharged from the bowl. This frequently happens when smoking a pipe in the wind or when the pipe is placed on a table or other support.

One of the greatest objections to the use of tobacco cartridges in the ordinary smoking pipe and in the smoking pipes provided especially for receiving said cartridges, is the great ditliculty of securing the necessarily tight fit between the cartridge and the pipe bowl. The cartridges are not circular in cross section. It is impossible to force the cartridge into a bowl of sufficiently smaller diameter than the cartridge to compact the cartridge and bring it to a true circular form in cross section and to secure the necessary tight fit between the cartridge and the bowl. When this is attempted the cartridge is either broken or is allowed to project a considerable distance beyond the end of the pipe. This, of course, largely de- 'stroys the value of the cartridge as a smokers article, is very unsightly and results in considerable waste of tobacco. The prime objects of using pipe charges in the form of cartridges are the economy in tobacco and the ease of charging the pipe.

It is equally objectionable where it is attempted to smoke the tobacco cartridges in a pipe the bore of which easily and freely receives the tobacco cartridge. If the fit between the cartridge and the Wall of the Specification of Letters Patent.

pipe bowl is not sufficiently air-tight the smoke travels along the sides of the cartridge, burning it out in grooves and permitting too great a proportion of air to pass to the smoker, thereby destroying the taste of the tobacco and producing the unpleasant tongue-burning effect. To secure the best results from a smoking pipe the draft and smoke must be carried through the tobacco charge, and the charge must be thoroughly and tightly packed. This proper packing of the tobacco in the pipe is most essential in order to secure the desired pleasing results from a smoke. As hereinbefore stated, if the smoke is mixed with any perceptible quantity of air, the smoke will produce the unpleasant bite or biting sensation on the tongue, whereas if the pipe is properly packed and the smoke is drawn through the tobacco charge, this biting effect is eliminated, or substantially so. 7

In the use of a cartridge charge for a smoking pipe it is most essential that the cartridge be fitted very tightly in the pipe bowl, and this is not possible with the ordinary forms of pipes on the market, or with pipes especially designed for receiving the tobacco cartridges.

One of the principal objects of the invention is to provide a pipe of an essentially novel construction and wherein the tobacco charge will be inserted at the stem end of the pipe instead of at the open or bowl end thereof, the stem being detachable from the body of the pipe for this purpose.

Another object of the invention is to provide a pipe body in which the tobacco charge will be placed therein at the stem end, the

stem serving as means for forcing the charge tightly into the pipe bowl. This is the reverse of the ordinary operation of charging a pipe. It is manifest that in charging a pipe inv this manner a fresh charge of tobacco may be placed in the pipe bowl and forced inwardly toward the fire. This wholly eliminates the accumulation of what is termed the heel in the bottom of the pipe bowl. It is well known that the accumulation of this heel is the disagreeable feature of pipe smoking. By charging the pipe from the rear the fresh tobacco is constantly forcing the heel of the previous charge toward the fire so that it will be consumed. Therefore, there can be no accumulation of a wet, soggy heel.

Another important object of this invention is to provide a pipe especially adapted to receive tobacco cartridges, the bowl of said pipe being so constructed that the cartridge will fit tightly therein at all points in its circumference, so-that the draft or smoke will pass through the tobacco charge and cannot pass around it or along the wall of the pipe bowl.

Another object of the invention is to provide a pipe bowl which extends inwardly into the pipe body from the stem end thereof, and tapers inwardly so that charges of tobacco in cartridge form may be placed therein and forced inwardly and home by means of the stem, said stem serving as a plunger. It is manifest that by tapering the pipe bowl toward its inner end and then forcing the cartridges therein, they will be compacted and brought to a true circular form in cross section, and the necessary tight fit between the cartridge and the wall of the bowl will be secured. This result is readily obtained by using the stem as a plunger for forcing the cartridges in position.

It is manifest that the pipe bowl may be made of any desired length to receive one or more cartridges, or any desired amount of tobacco, at a charge.

There are many other objects and advantages of the invention which need not be specifically set forth at this time, but which will fully hereinafter appear.

,Inthe drawing, Figure 1 is a longitudinal vertical sectional view, showing the pipe bowl adapted to receive a large charge of tobacco, or two of the ordinary cartridges of commercial size Fig. 2 a similar view of a pipe adapted to receive a single cartridge, or a small charge of tobacco;

, Fig. 3 a detail View of the end of the stem shown in Fig. 1; and

Fig. i a detail view of the end of the stem shown in Fig. 2.

Fig. 5 is a view similar to Fig. 2, showing a cartridge in the bowl.

Referring to the various parts by numerals, 1 designates the body of the pipe which is apertured longitudinally from end to end to form the pipe bowl 2 and the draft passage 3 at the outer end of said body part. The pipe bowl is largest in diameter at the inner or stem-receiving end of the body, and taperstoward its forward end. The draft opening and passage 3 is preferably considerably smaller in diameter than the pipe bowl, the forward end of the bowl being contracted, and extended somewhat laterally to form this draft passage. It will, of course, be understood that the forward or outer end of the pipe may be constructed of any suitable shape in order to give the pipe a pleasing appearance and to produce the slightly restricted draft passage. As shown in Fig. 1, the bowl is of considerable length and is adapted to receive a large charge of tobacco, or two of the ordinary commercial size tobacco cartridges now so largely used by pipe smokers, said cartrid es being arranged end to end in the pipeowl as indicated, the forward end of the innermost cartridge extending close to the draft-passage in order that it may be readily lighted, and also so that the ashes may be readily removed, or knocked out through the said passage.

The stem a of the pipe is tapered to correspond to the taper of the pipe bowl, and is adapted to extend therein a suitable distance and to serve as a plunger for forcing inwardly the tobacco charge. This stem, of course, must be so tapered that it will form a tight joint with the body of the pipe after it has been forced the desired distance into the pipe bowl. The stem carries the usual bit 5, and the bit and the stem are apertured longitudinally to provide smoke passages.

The smoke passages at the inner end of the stem may be arranged in any desired manner. As shown in Figs. 1 and 3, the forward or inner end of the stem is provided with the cross grooves 6 and 7. The ends of the groove 6 are connected by longitudinally extending grooves 8 to an annular groove 9 which extends around the end of the stem. A transverse passage 10 extends through the stem and intersects the groove 9. This aperture 10 is connected to the longitudinal smoke passage 11. In this way the smoke will enter the cross grooves (3 and 7, and then travel through the short longitudinal grooves 8 into the annular passage 9. From this passage it will enter the transverse aperture 10 and thence flow through the longitudinal smoke passages in the stem and bit, or mouth-piece.

In Figs. 2 and 4 is shown a slightly different arrangement of smoke passages in the inner end of the stem, and it will, of course, be understood that these passages may be arranged in any manner desired.

-The form of pipe shown in Fig. 2 is substantially the same as that shown in Fig. 1, with the exception that the pipe bowl is short and is designed to receive a small charge of tobacco, or only one tobacco cartridge.

The method or manner of using a pipe constructed as described herein and as shown in the drawing, will be obvious to those familiar with. pipe smoking. The stem is detached from the pipe bowl and the tobacco charge placed therein, and then the stem is forced into the bowl to pack the charge therein. As the charge is burned the ashes may be detached from the unburned tobacco by means of any suitable device inserted through the draft-passage, and then of course, the detached ashes may be discharged through said passage. When receiving end of the pipe bowl and forcedtherein by the plunger stem. This will carry the previously inserted chargeto the li htin ooenin and lace the fresh cartridge at the rear or base of the bowl.

One of the great advantages of providing a pipe bowl capable of receiving two cartridges is that the innermost cartridge, which is always the fresh cartridge, serves as a filter for the smoke. Another advantage is that the hot smoke passing through the innermost cartridge brings it into a prime condition for smoking. It has been determined that this preliminary heating or slight parching of the tobacco produces very desirable results.

By reason of the peculiar construction of the pipe bowl, and the provision of a restricted lighting opening, and draft-passage, the pipe may be smoked in the wind without danger of the fire being blown out of the pipe, and without interfering with the ease and comfort of the smoker. A further advantage of a pipe of the construction described herein is that the ash and fire will not drop out or accidentally be discharged from the pipe. Because of this the pipe may be safely placed in the pocket, lighted, and it may be laid down on the desk or table, or in any desired place without danger. A pipe of this construction may be safely smoked in places where the smoking of pipes of the usual construction is prohibited.

From the foregoing description of the method of using a pipe constructed in ac cordance with this invention it is manifest that there will be no loss of tobacco, and that all of the tobacco placed in the pipe will be burned. The unburned portion of one charge will be forced toward the lighting opening when a fresh charge is placed in the pipe. This economy in tobacco is important in addition to the great advantage of having a charge of fresh clean tobacco inserted between the stem and the lighted portion of the charge, which fresh charge serves as an efficient filter for the smoke.

It will be observed also that the combined lighting and draft passage 3 tapers inwardly from the narrowest part of its throat until it meets the smaller end of the charge-receiving chamber; this is an advantageous construction in that it not only in sures the charge being held well back from the outer end of the draft passage, but also enables the ashes to be readily jarred out from time to time as the charge is consumed; and it will be further observed that the forward taper of the charge-holding chamber insures the charge being held in place until it is entirely consumed, if the smoker continues smoking for that length of time. It will be further understood, of course, that the charge of tobacco may occasionally be too short to be rammed home by the end of the stem and that in such case the charge may be rammed by the finger or thumb, but in every case the tapering of the interior of the bowl toward the lighting end will insure the necessary circumferential packing of the charge.

What I claim is:

l. A smoking pipe comprising a body part formed with a pipe bowl tapering from its inner end toward its outer end, said body part being formed with a restricted draft passage communicating with the outer smaller end of the pipe bowl, and a pipe stem adapted to fit the inner larger end of the bowl and to form a plunger adapted to force the tobacco charge into the tapered bowl, whereby said charge will be condensed and packed.

2. A smoking pipe comprising a body part formed with a pipe bowl tapering from its inner end toward its outer end, said body part being formed with a laterally eX- tending restricted draft passage communicating with the outer smaller end of the pipe bowl, and a tapered pipe stem adapted to fit the inner larger end of the bowl to form a plunger adapted to force the tobacco charge into the tapered bowl, whereby said charge will be condensed and packed.

3. A smoking pipe comprising a body part formed with a pipe bowl extending from its innerend toward its outer end, said body part being formed with a laterally extending restricted draft passage communieating with the outer end of the pipe bowl, and a pipe stem adapted to fit the inner end of the bowl to form a plunger adapted to force the tobacco charge into the bowl, whereby said charge will be condensed and packed.

4:. A smoking pipe comprising a body part formed with a bowl having a restricted lighting and draft passage at one end and a charging opening at its other end, said bowl tapering from the charging opening toward the lighting opening, and a stem fitting within and closing the charging opening, whereby said stem will serve as a plunger to compress and pack the tobacco charge.

5. A smoking pipe comprising a body part formed with a tobacco chamber and a restricted draft and lighting passage extending inwardly from the forward end of the body part and communicating with the forward end of the tobacco chamber, and a pipe stem fitting in and closing the inner or rear end of the pipe bowl, said stem being formed with 'a'longitudinally extending smoke passage and with transverse smoke-collecting grooves on its inner face, and also with grooves connecting the outer ends of these transverse grooves with the longitudinally extending smoke passage.

6. A smoking pipe comprising a body part formed with a tobacco chamber, and a restricted draft and lighting passage extending inwardly from the forward end of the body part and communicating with the forward end of the tobacco chamber, and a pipe stem fitting in and closing the inner or rear end of the pipe bowl, said stem being formed with a longitudinally extending smoke passage and with transverse smokecollecting grooves on its inner face, an annular groove formed in said stem near its forward end, transverse passages connecting said groove with the longitudinally excopiessof' this patent may be obtained for tending smoke passage, and longitudinally extending grooves connecting the outer ends of some of the transverse grooves with said annular groove.

7 A smoking pipe comprising a body part formed with a bowl having a lighting and draft passage at its outer end and a charging opening at its other end, the interior of the bowl being tapered from the charging opening toward the draft passage, whereby the tobacco charge will be circumferentially compressed when it is rammed into the bowl, and a stem removably fitted to the charging end of the bowl, said lighting and draft passage being turned laterally with respect to the tapered bowl and being tapered inwardly to meet the forward end of the charge-holding part of the bowl.
